Instructions
Mix all the ingredients very well in a large mixing bowl, then transfer to a storage jar. I recommend using a glass jar that seals very well. Store for up to 2-3 months at room temperature.
Notes
DISCLAIMER: I strongly recommend using a digital kitchen scale to measure your flour for this recipe as cup measurements are not always precise.
